Herichthys carpinte has large blue-green pearls (these form a mosaic pattern in the rarer Escondido variant) whereas Herichthys cyanoguttatus is distinctively marked with much tinier spots. Also, H. carpinte very rarely exceeds 8" in length, whereas H. cyanoguttatus commonly gets to 12" long.
Yours are most likely hybrids between H. carpinte and H. cyanoguttatus, as are most of the fish sold as "Texas Cichlids" in the hobby today.
